Sanofi announced the replacement of Jean-Baptiste Chasseloup de Chatillon, its financial director for five years, by François-Xavier Roger, who previously held the same position at Nestlé. The stock price of the French pharmaceutical laboratory fell by almost 20% last October, after a downward revision of its profitability objective by 2025.

The decline, assures Paul Hudson, the managing director of Sanofi, is the price to pay to focus on innovation and once again become a world leader in pharmacy.
